Anyone got it working so that it sharpens and scales?
I followed this guide:

But at step 5 the indicator stays blue (i.e. NIS is sharpening the image but not scaling it). I'm not clear what options (if any) I can set to make the game not do the scaling itself - the graphic options don't seem to include 'let someone else do the upscaling' so I chose the internal (default) upscaler.
